CROSS-REFERENCE TO PRIOR APPLICATION

Priority is claimed to Chinese Patent Application No. 202111628872.9, filed on Dec. 28, 2021, the entire disclosure of which is hereby incorporated by reference herein.

FIELD

The present invention relates to the field of vaporization technologies, and in particular, to an electronic vaporization device and a vaporizer.

BACKGROUND

An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in an air medium. The aerosol can be absorbed by the body through the respiratory system, providing a user with a novel and alternative absorption manner, for example, an electronic vaporization device generating the aerosol by baking and heating aerosol-generation substrates such as herbs or pastes. The electronic vaporization device is applied in different fields to deliver an inhalable aerosol to the user, replacing a conventional product form and an absorption manner.

Generally, in an electronic vaporization device, a liquid storage cavity is sealed by sleeving a silicone member on a vaporization assembly, and the seal effect of the assembly manner is relatively good. However, if the seal effect is to be ensured during the assembly of the structure, a seal member needs to be pressed down to a certain extent, and when the seal member is pressed down, compressed air is formed in the lower liquid storage cavity. After the liquid storage cavity is sealed, the compressed air that is squeezed in the liquid storage cavity cannot be discharged. Then, the compressed air can only squeeze an aerosol-generation substrate in the liquid storage cavity, and the aerosol-generation substrate is squeezed out under the action of pressure, resulting in the problem of liquid leakage.

SUMMARY

In an embodiment, the present invention provides an electronic vaporization device, comprising: a housing assembly; a vent tube arranged in the housing assembly, and a liquid storage cavity with an opening on one end being defined and formed between the housing assembly and the vent tube; and a seal member arranged on the vent tube and sealing an opening of the liquid storage cavity, wherein an exhaust channel configured for assembly is formed between the seal member and the vent tube, wherein the seal member and the vent tube are assembled, and wherein a seal is formed between the seal member and the liquid storage cavity.

Referring to FIG. 1 to FIG. 2 , in an embodiment of the present invention, an electronic vaporization device 100 is provided, which is configured to heat and vaporize an aerosol-generation substrate.

Referring to FIG. 2 to FIG. 4 , the electronic vaporization device 100 includes a housing assembly 10, a vent tube 20, and a seal member 50. The vent tube 20 is sleeved at intervals in the housing assembly 10, and a liquid storage cavity 11 with an opening on one end is defined and formed between the housing assembly 10 and the vent tube 20, and the liquid storage cavity 11 is configured to store the aerosol-generation substrate. The seal member 50 is sleeved on the vent tube 20 and seals the opening of the liquid storage cavity 11. After liquid is injected into the liquid storage cavity 11, the seal member 50 can be configured to seal the liquid storage cavity 11. In addition, an exhaust channel for assembly is formed between the seal member 50 and the vent tube 20, and a seal is formed between the seal member 50 and the liquid storage cavity 11 after the seal member 50 and the vent tube 20 are assembled. That is, when the seal member 50 is assembled, the seal member 50 is sleeved on the vent tube 20 and gradually moves downward, and an exhaust channel is formed between the seal member 50 and the vent tube 20. The exhaust channel causes the liquid storage cavity 11 to be in communication with the outside, so that the air in the liquid storage cavity 11 can be discharged to the outside, preventing the liquid storage cavity 11 from being squeezed to form excessive compressed air.

After the seal member 50 and the vent tube 20 are assembled, the seal member 50 is sealed with the liquid storage cavity 11. A fluid channel that is in communication with the liquid storage cavity 11 is no longer formed between the seal member 50 and the vent tube 20, so as to completely seal the liquid storage cavity 11 and prevent the aerosol-generation substrate in the liquid storage cavity 11 from leaking. In this way, the air in the liquid storage cavity 11 is discharged through the exhaust channel in a process of pressing down and mounting the seal member 50 to prevent excessive compressed air from remaining in the liquid storage cavity 11, and to prevent the compressed air remaining in the liquid storage cavity 11 from squeezing the aerosol-generation substrate out of the liquid storage cavity 11 after the seal member 50 and the vent tube 20 are assembled, thereby preventing the electronic vaporization device 100 from leaking liquid.

After the seal member 50 and the vent tube 20 are assembled, a fluid channel that is in communication with the liquid storage cavity 11 is no longer formed between the seal member 50 and the vent tube 20. The seal member 50 completely seals the liquid storage cavity 11 to prevent the aerosol-generation substrate in the liquid storage cavity 11 from leaking. In this way, the air in the liquid storage cavity 11 is discharged through the exhaust channel in a process of pressing down and mounting the seal member 50 to prevent excessive compressed air from remaining in the liquid storage cavity 11, and to prevent the compressed air remaining in the liquid storage cavity 11 from squeezing the aerosol-generation substrate out of the liquid storage cavity 11 after the seal member 50 and the vent tube 20 are assembled, thereby preventing the electronic vaporization device 100 from leaking liquid.

In some embodiments, A surface of at least one of the seal member 50 and the vent tube 20 that faces an other is provided with an exhaust groove 60, and the seal member 50 includes a first seal end 51 and a second seal end 55 that are arranged at two opposite ends of the exhaust groove 60 in the assembly direction; and when the seal member 50 and the vent tube 20 are assembled, the exhaust channel is jointly configured and formed by a gap between the first seal end 51 and the vent tube 20, a gap between the second seal end 55 and the vent tube 20, and the exhaust groove 60. That is, when the seal member 50 is sleeved and mounted on the vent tube 20, two opposite ends of the seal member 50 in the assembly direction of the seal member 50 are the first seal end 51 and the second seal end 55 respectively. There is a first gap between the first seal end 51 and the vent tube 20, and a second gap is formed between the second seal end 55 and the vent tube 20. In addition, at least one of the seal member 50 and the vent tube 20 is provided with an exhaust groove 60, and the exhaust groove 60 is in communication with the first gap and the second gap. In this way, an exhaust channel is formed when the seal member 50 is mounted, and the air in the liquid storage cavity 11 can flow to the outside through the exhaust channel, so as to prevent liquid leakage caused by accumulation of compressed air in the liquid storage cavity 11.

Further, the seal member 50 is at least partially sleeved between the housing assembly 10 and the vent tube 20 to seal the liquid storage cavity 11. That is, one end of the seal member 50 is sealed with the housing assembly 10, and an other end of the seal member 50 is sealed with the vent tube 20, so as to seal the liquid storage cavity 11 and prevent the aerosol-generation substrate in the liquid storage cavity 11 from leaking. In addition, a seal formed between the seal member 50 and the vent tube 20 after the assembly is completed includes at least one of the following forms: the first seal end 51 forms a seal with the vent tube 20; and the second seal end 55 forms a seal with the vent tube 20. After the seal member 50 and the vent tube 20 are assembled, the first seal end 51 forms a seal with the vent tube 20. In this way, there is no longer a gap between the first seal end 51 and the vent tube 20, thereby blocking a passage between the exhaust groove 60 and the outside, and preventing the aerosol-generation substrate in the liquid storage cavity 11 from leaking out from the exhaust groove 60.

Alternatively, after the seal member 50 and the vent tube 20 are assembled, the second seal end 55 forms a seal with the vent tube 20. In this way, there is no longer a gap between the second seal end 55 and the vent tube 20, thereby blocking a passage between the liquid storage cavity 11 and the exhaust groove 60, and preventing the aerosol-generation substrate in the liquid storage cavity 11 from leaking out from the exhaust groove 60. Alternatively, after the seal member 50 and the vent tube 20 are assembled, the first seal end 51 forms a seal with the vent tube 20, and the second seal end 55 forms a seal with the vent tube 20. In this way, there is no longer a gap between the first seal end 51 and the vent tube 20, and simultaneously there is no longer a gap between the second seal end 55 and the vent tube 20, thereby effectively blocking the exhaust channel and preventing the aerosol-generation substrate in the liquid storage cavity 11 from leaking out.

Referring to FIG. 3 , further, the seal member 50 is provided with an assembling hole 53 in the assembly direction, and the seal member 50 is sleeved on the vent tube 20 through the assembling hole 53, so that the seal member 50 is sleeved and assembled with the vent tube 20.

In some embodiments, a surface of at least one of a hole wall of the assembling hole 53 on the seal member 50 and the vent tube 20 that faces an other is provided with an exhaust groove 60, so as to form an exhaust channel in a mounting process of the seal member 50 by using the exhaust groove 60. In addition, after the seal member 50 is assembled, the exhaust groove 60 no longer causes the liquid storage cavity 11 to be in communication with the outside, so as to prevent the aerosol-generation substrate in the liquid storage cavity 11 from leaking from the exhaust groove 60.

Referring to FIG. 2 to FIG. 4 , optionally, in the seal member 50, an exhaust groove 60 is provided on the surface of the hole wall of the assembling hole 53 that faces the vent tube 20. When the seal member 50 is assembled, the seal member 50 is sleeved on the vent tube 20 and moves downward in an axial direction of the vent tube 20. There is a first gap between the first seal end 51 and the vent tube 20 and a second gap between the second seal end 55 and the vent tube 20 respectively. The airflow in the liquid storage cavity 11 can flow to the second gap through the first gap and the exhaust groove 60, and then flow to the outside. In this way, the air in the liquid storage cavity 11 is guided to be discharged by the exhaust groove 60 on the seal member 50. After the seal member 50 is assembled, at least one of the first seal end 51 and the second seal end 55 is sealed with the vent tube 20, and at least one of the first gap and the second gap no longer exists. The exhaust groove 60 on the seal member 50 cannot cause the liquid storage cavity 11 to be in communication with and the outside, thereby preventing the aerosol-generation substrate in the liquid storage cavity 11 from leaking from the exhaust groove 60.

That is, an exhaust groove 60 is provided on the hole wall of the assembling hole 53. When the seal member 50 is gradually sleeved downward on the vent tube 20, the first gap between the first seal end 51 and the vent tube 20 and the second gap between the second seal end 55 and the vent tube 20 are gradually decreased. Before the first gap and the second gap are not completely reduced to zero, the air in the liquid storage cavity 11 can further be allowed to flow from the exhaust groove 60 to the outside until either of the first gap and the second gap is completely reduced zero. After the seal member 50 is assembled, the exhaust groove 60 cannot cause the liquid storage cavity 11 to be in communication with and the outside, so that the liquid storage cavity 11 is sealed to prevent the liquid storage cavity 11 from leaking.

Referring to FIG. 2 and FIG. 5 to FIG. 6 , optionally, an exhaust groove 60 is provided on the surface of the vent tube 20 that faces the hole wall of the assembling hole 53. That is, an outer peripheral surface of the vent tube 20 is provided with an exhaust groove 60. When the seal member 50 is assembled, the seal member 50 is sleeved on the vent tube 20 and moves downward in an axial direction of the vent tube 20. There is a first gap between the first seal end 51 and the vent tube 20 and a second gap between the second seal end 55 and the vent tube 20 respectively. The airflow in the liquid storage cavity 11 can flow to the second gap through the first gap and the exhaust groove 60, and then flow to the outside. In this way, the air in the liquid storage cavity 11 is guided to be discharged by the exhaust groove 60 on the vent tube 20. After the seal member 50 is assembled, at least one of the first seal end 51 and the second seal end 55 is sealed with the vent tube 20, and at least one of the first gap and the second gap no longer exists. The exhaust groove 60 on the vent tube 20 cannot cause the liquid storage cavity 11 to be in communication with the outside, thereby preventing the aerosol-generation substrate in the liquid storage cavity 11 from leaking from the exhaust groove 60.

That is, an exhaust groove 60 is provided on the outer peripheral surface of the vent tube 20. When the seal member 50 is gradually sleeved downward on the vent tube 20, the first gap between the first seal end 51 and the vent tube 20 and the second gap between the second seal end 55 and the vent tube 20 are gradually decreased. Before the first gap and the second gap are not completely reduced to zero, the air in the liquid storage cavity 11 can further be allowed to flow from the exhaust groove 60 to the outside until either of the first gap and the second gap is completely reduced zero. After the seal member 50 is assembled, the exhaust groove 60 cannot cause the liquid storage cavity 11 to be in communication with and the outside, so that the liquid storage cavity 11 is sealed to prevent the liquid storage cavity 11 from leaking.

In some embodiments, the seal member 50 includes a body 52 and a limiting portion 54. The body 52 is provided with an assembling hole 53, and the limiting portion 54 is arranged on the first seal end 51 and protrudes from the hole wall of the assembling hole 53. The vent tube 20 is sleeved in the assembling hole 53 and abuts against the limiting portion 54 in a limiting manner after the assembly is completed, and seals the first seal end 51 and the vaporization assembly 30. A limiting portion 54 is arranged on the first seal end 51 of the seal member 50. In a process of pressing down and mounting the seal member 50, the seal member 50 moves down in the axial direction of the vent tube 20, and there is a gap between the limiting portion 54 and the vent tube 20. After enters the exhaust groove 60, the air in the liquid storage cavity 11 can flow to the outside through the first gap between the limiting portion 54 and the vent tube 20 to be discharged. When the seal member 50 continues to move downward in the axial direction of the vent tube 20 until the limiting portion 54 abuts against the vent tube 20 in a limiting manner, the seal member 50 can no longer move relative to the vent tube 20, and the seal member 50 is assembled. In addition, there is no longer a first gap between the limiting portion 54 and the vent tube 20, so that a seal is formed between the vent tube 20 and the limiting portion 54. Therefore, a seal is formed between the first seal end 51 and the vaporization assembly 30, and the exhaust groove 60 cannot be in communication with the outside, thereby preventing the aerosol-generation substrate from leaking in the liquid storage cavity 11.

Referring to FIG. 3 and FIG. 5 to FIG. 6 , further, one end of the vent tube 20 that is arranged at the opening of the liquid storage cavity 11 is provided with an inwardly bent flange 321. The flange 321 abuts against the limiting portion 54 in a limiting manner in the axial direction of the vent tube 20. An inwardly bent flange 321 is arranged on an axial end portion of the vent tube 20, so that when the vent tube 20 abuts against the limiting portion 54, the entire flange 321 abuts against the limiting portion 54, a contact area is increased, and the seal performance to the exhaust groove 60 is improved.

Referring to FIG. 3 and FIG. 5 , in some embodiments, the assembling hole 53 includes a mounting section 532 and an outwardly expanding opening section 534. The mounting section 532 is located between the outwardly expanding opening section 534 and the limiting portion 54. A diameter of the outwardly expanding opening section 534 is greater than a diameter of the mounting section 532, which is equivalent to that one end of the assembling hole 53 that is away from the limiting portion 54 is configured as the outwardly expanding opening section 534, and a pore size of the assembling hole 53 is enlarged outward. In this way, in a process of mounting the seal member 50, on the one hand, it is convenient for the seal member 50 to be sleeved on the vent tube 20 through the outwardly expanding opening section 534, and on the other hand, a distance between an inner wall of the outwardly expanding opening section 534 and the vent tube 20 is relatively large, which facilitates the air in the liquid storage cavity 11 to flow from the outwardly expanding opening section 534 to the exhaust groove 60, thereby increasing an exhaust volume.

In some embodiments, the vent tube 20 includes a step surface 326. The vent tube 20 is sleeved in the assembling hole 53, and after the assembly is completed, the second seal end 55 abuts against the step surface 326 and seals the second seal end 55 and the vaporization channel 35. The vent tube 20 is arranged into a first section and a second section with different diameters and a bent section connected between the first section and the second section. An outer surface of the bent section forms a step surface, the first section with a smaller diameter is sleeved in the assembling hole 53 of the seal member 50, and the step surface 326 faces the second seal end 55. When the seal member 50 is gradually pressed down and sleeved, the second gap between the second seal end 55 and the step surface 326 is gradually reduced. If there is still a second gap between the second seal end 55 and the step surface 326, the air in the liquid storage cavity 11 can enter the exhaust groove 60 through the second gap, and then flow to the outside through the first gap between the first seal end 51 and the limiting portion 54.

After the seal member 50 is assembled, the second seal end 55 completely abuts against the step surface 326, and there is no longer a gap between the second seal end 55 and the step surface 326, blocking the communication between the liquid storage cavity 11 and the exhaust groove 60, so that a seal is formed between the second seal end 55 and the vaporization assembly 30, to prevent the aerosol-generation substrate in the liquid storage cavity 11 from leaking after entering the exhaust groove 60.

Further, an outwardly expanding opening section 534 is located at the second seal end 55, and the vent tube 20 is sleeved in the assembling hole 53 and an inner wall of the outwardly expanding opening section 534 abuts against the step surface 326 in a limiting manner after the assembly is completed, so as to form a seal between the second seal end 55 and the vent tube 20.

In addition, the step surface 326 on the vent tube 20 and the inner wall of the outwardly expanding opening section 534 are both configured as inclined surfaces that match each other, which is equivalent to a step surface 326 being connected obliquely between the first section and the second section. The outwardly expanding opening section 534 and the step surface 326 match each other and are both the inclined surfaces, and the outwardly expanding opening section 534 and the step surface 326 can abut against each other in a limiting manner in the axial direction of the vent tube 20, and simultaneously prevent too many sharp corners from causing a relatively large wind resistance and affecting the airflow. It is convenient for airflow to flow into the second gap between the inner wall of the outwardly expanding opening section 534 and the step surface 326 when the seal member 30 is mounted.

Further, the first air outlet channel 72 on the top cover 70 is in communication with the inside of the vent tube 20, and a vaporization member 34 is sleeved in the vent tube 20. The aerosol formed in the vaporization channel 35 of the vaporization member 34 can flow to the first air outlet channel 72 through the vent tube 20 to be inhaled by the user.

Referring to FIG. 7 to FIG. 8 , in some other embodiments, the housing assembly 10 includes a second housing 14 and a liquid storage shell 16, and the vent tubes 20 are sleeved at intervals in the liquid storage shell 16. A liquid storage cavity 11 with an opening on one end is defined and formed between the liquid storage shell 16 and the vent tube 20. The seal member 50 is arranged at the opening of the liquid storage cavity 11 and is sealedly sleeved between the liquid storage shell 16 and the vent tube 20. In this way, the liquid storage shell 16, the vent tube 20, and the seal member 50 are combined to effectively store the aerosol-generation substrate in the liquid storage shell 16. In addition, the second housing 14 is sleeved outside the liquid storage shell 16 and the seal member 50, and the second housing 14 is provided with a second air outlet channel 141 that is in communication with the inside of the vent tube 20. Equivalently, the liquid storage shell 16, the seal member 50, and the vent tube 20 are combined together to be sleeved in the second housing 14 as a whole. In addition, a second air outlet channel 141 that is in communication with the inside of the vent tube 20 is formed on the second housing 14, and the vapor formed in the vent tube 20 flows from the second air outlet channel 141 to the mouth of the user.

Further, the electronic vaporization device 100 further includes a battery core base 80, and the second housing 14 is detachably connected to the battery core base 80. Equivalently, the liquid storage shell 16, the vent tube 20, the vaporization assembly 30, and the seal member 50 are combined and sleeved in the first housing 12 to form a vaporizer 101. The first housing 12 is detachably connected to the battery core base 80, so that the vaporizer 101 can be detachably connected to the battery core base 80, so as to facilitate the replacement of the vaporizer 101.

In an embodiment of the present invention, a vaporizer 101 is further provided, and the vaporizer 101 includes the liquid storage shell 16, the vent tube 20, and the seal member 50. The vent tube 20 is sleeved at intervals on the vent tube 20 in the liquid storage shell 16, and a liquid storage cavity 11 with an opening on one end is defined and formed between the liquid storage shell 16 and the vent tube 20. The seal member 50 is sleeved on the vent tube 20 and seals the opening of the liquid storage cavity 11. The liquid storage cavity 11 is configured to store the aerosol-generation substrate. After liquid is injected into the liquid storage cavity 11, the seal member 50 can be configured to seal the liquid storage cavity 11.

An exhaust channel for assembly is formed between the seal member 50 and the vent tube 20, and a seal is formed between the seal member 50 and the liquid storage cavity 11 after the seal member 50 and the vent tube 20 are assembled. That is, when the seal member 50 is assembled, the seal member 50 is sleeved on the vent tube 20 and gradually moves downward, and an exhaust channel is formed between the seal member 50 and the vent tube 20. The exhaust channel causes the liquid storage cavity 11 to be in communication with the outside, so that the air in the liquid storage cavity 11 can be discharged to the outside, preventing the liquid storage cavity 11 from being squeezed to form excessive compressed air.

After the seal member 50 and the vent tube 20 are assembled, a fluid channel that is in communication with the liquid storage cavity 11 is no longer formed between the seal member 50 and the vent tube 20, so as to completely seal the liquid storage cavity 11 to prevent the aerosol-generation substrate in the liquid storage cavity 11 from leaking. In this way, the air in the liquid storage cavity 11 is discharged through the exhaust channel in a process of pressing down and mounting the seal member 50 to prevent excessive compressed air from remaining in the liquid storage cavity 11, and to prevent the compressed air remaining in the liquid storage cavity 11 from squeezing the aerosol-generation substrate out of the liquid storage cavity 11 after the seal member 50 and the vent tube 20 are assembled, thereby preventing the electronic vaporization device 100 from leaking liquid.
